operation. These devices are
designed to be used in high-performance
memory-decoding or data-routing applications
requiring very short propagation delay times. In
high-performance memory systems, these
decoders can be used to minimize the effects of
system decoding. When used with high-speed
memories utilizing a fast enable circuit, the delay
times of these decoders and the enable time of the
memory usually are less than the typical access
time of the memory. This means that the effective
system delay introduced by the decoders is
negligible.
